Components with inline templates (with commented out 'templateUrl')

Components with _commented-out templateUrl_ still throw a build error. For example, from this simple component

@Component({
selector: 'common-html-entry',
// templateUrl: 'common-html-entry.html',
template: `

`
})
export class CommonHtmlEntryComponent { ...

I get the following build error:

[10:33:00] Starting 'inline-resources'...
An error occured: { Error: ENOENT: no such file or directory,

It looks like `templatUrl` takes precedence (even it it's commented out) over the inline html template.

Start in tools/gulp/inline-resources.js, especially the logic around lines 70-83, and reproduce the issue with the component shown in the report. Verify that a commented-out templateUrl no longer causes a missing-file error and that the inline template is used successfully.
